Wheely good builder!

Wheely good builder! (4/6)

    No Air Filter

    This is a suggestion, ive not tried it. Firstly use a long straight edge, say length of baton between scuttle top and nosecone edge to measure how much clearance you actually have. Then look at at thin universal pancake filters, like https://www.ebay.co.uk/itm/311892226985 to use. Such a filter could even be made thinner by trimming the sponge and cage, but obviusly too thin will strangle the carb. The other challenge will be to find a way to mount it on the carb. You could cut a round hole a bit smaller, say 20mm, than the inlet diameter, then cut lots of radial slots round the circumference, 10mm deep, then bend each out at right angles. This would let the filter base slot over the carb inlet with a jubilee clip around the all the bent down bits to fix it to the carb. Perhaps some tape around this would then make an air tight seal. The filter could be mounted upside down so that the dome nuts are underneath, leaving a totally smooth upper surface.
  2. Bit late to this topic.... I attach a couple of snaps from my car. The second is the standard pedals, to see the standard spacing, yours look to have an offset brake pedal, but that could be perspective. The first is from above with the pedals installed. You see that the throttle is seperate, not installed, so could be moved easily in all directions. What is not easy is changing the height or spacing of the clutch/brake pedals. The clutch quadrant position is fixed by the release mechanism in the cable guide, and the brake pedal top by the alignment of the master cylinder rod. Moving the whole assembly up is theoretically possible, with spacers, but the whole top cover (not shown) would need to be raised, all the brake pipes extended, and then not so high as for the servo or fluid reservoir to hit the bonnet. Lowering the floor and/or altering the pedals is going to be easier, although shortening pedals will of course alter the leverage and range of motion somewhat, e.g. shorter clutch pedal would be harder to release smoothly.
  3. Oh, just look at the S7 build manual, (I have an Exmo) and there is a small difference, the routing of the S7 cable looks to be through the sloping panel as shown in the build manual that I attached before in a different thread https://www.rhocar.org/index.php?/forums/topic/50972-s7-handbrake-cable/#comment-413125
  4. Have a look at this diagram, of the Sierra rear subframe from above. See, the cable route is pretty much symmetric, left to right. From the wheel backplate on top of the trailing arm and then through a hole in a flat plate part of the subframe really close to the pinion UJ (not shown here), so you have to imagine the prop shaft between the loop in the cable, out of frame bottom right to the pinion flange (shown). On the Sierra the nylon adjusters use a bracket from the body, but on your car the adjusters use the aformentioned holes in the flat part of the subframe. Out of frame there is an exposed loop of inner cable that goes through a metal yoke. The centre of the yoke is attached to a single rod that goes to the bottom of the handbrake. When the handbrake is applied the yoke moves forward and tightens the cable, if the yolk is properly lubricated any difference in L/R tension will be equalised by the cable slipping through the yoke. Because the cable is shorter than the one shown here, the yoke will be really close to and just above the prop and UJ, just inside the hole through which the prop appears from the transmission tunnel. If you use the "cut the cable in the middle" method of fitting then whatever you use to rejoin the ends has to fit in this restricted space between where the cable comes through the subframe and the yolk, without fouling the UJ or preventing enough slippage through the yolk to equalise the R/L tension. If you shorten by removing one of the end pips, then you have to be very careful to pre thread the items along the length of the cable before you weld on the new pip. Hope this helps.
  5. Something in your description of where the wires go, does not sound good to me. Unfortunately you don't say which wire is + (I'm assuming black) and so green is -ve which would match the colours used in a standard sierra loom. The way a coil works is that with ignition on, and engine not running (and points closed if you are using points) then the +ve should be live via the ignition and the -ve should run to earth but not directly, it must run to earth via the ignition module (or points). In this state the low tension windings in the coil are energized and there is magnetic energy in the coil core. When the engine is running, the ignition module (or points) suddenly disconnect the -ve from earth, this causes a suddend collapse of magnetism in the core, and the energy is dissapated in the high tension coil, giving a high voltage pulse that is used for a spark. The dissconnection only last a short while, so that the coil can recharge with energy for the next spark ... and so on. So ... if the -ve connection on your coil is directly connected to earth, there will be no interruption in the circuit and so no spark. In the Sierra loom the black comes from the ignition switch, the green runs to the electronic ignition module, which then connects the coil to earth but intermittently disconnects when a spark is required, depending on all the other inputs to the ignition module.
  6. Just browsed the parts catalogue, I think you need to purchase a Ford part that you will find by either using the number 1644433 or the code 83BB2A603AG, just put "Ford" in front and search with your favourite search engine should pull up a Sierra MK1 handbrake cable assembly..... then find the best price/quality etc.
  7. I think that you need to buy a Sierra handbrake cable MK1 or Mk2 probably ok, because it will need to be shortened. There is no "off the shelf" part I am attaching a pdf of the three pages covering the handbrake, from the build manual. It is just about legible. S7-Handbrake-Build.pdf
  8. I am wondering if you are checking your car against the IVA manual ? In the section on seat belts, there is the following:- Note 2: A suitable single bolt fixing of adequate strength would be, for example, a bolt of at least 11mm (7/16") diameter of grade 8.8 (the grade may not be shown on a bolt produced for a seat belt anchorage). Other bolt fixings may be acceptable providing they are of equivalent strength. Two adjacent seat belts may be secured by one bolt. In this case consideration must be given to the additional loads on the anchorage Just in case you have not looked at the IVA manual, HERE is a link to the current version (today 2023-10-14) on gov website.
  9. Potentially there are three areas that might be preventing the drum from coming off the hub. One is the edge of the drum around the hub, in your photo this is the start of the rusty bit, the hub being black paint. Wire brush the rust off and apply penetrating oil (WD40) to the joint area. The next thing might be the wheel studs, which the drum has to slip over, again wire brush the base of these and apply penetrating oil. The third area is harder to free. The brakes are self adjusting, each time the the handbrake is applied, see the manual. It is possible for the shoes to be tightly sitting in a "trench" formed by wear and rust build up on the inside drum edge, stopping it from coming over the shoe surface. You can tell this is the case, if when you try to lever the drum off, carefully with a broad screwdriver or tyre lever between the drum edge and backplate it seems to be free at the hub and wheel studs but keeps springing back on to the hub when you let the lever go. In this case you should try releasing the shoes as described in the manual. My copy does not just say "remove the drum" there is the following "it is possible to release the automatic adjuster mechanism by inserting a screwdriver through the small hole in the drum and pressing down on the ratchet (see illustrations). .(5.5b)..... but I dont see a small hole in your drum, look for it. Your brake adjuster looks to have the locking mechanism missing, someone has put a lump of something there to stop it unwinding itself. Again look at the manual especially at the "hand brake equalizer" see figure 29.3. The cable has to slide through here easily to even out tension between both sides. And like IanS says the cable will have been shortened by cutting a piece off and fixing a new ferrule. The build video shows how to drill a hole in the center of a piece of bolt thread, put the cut end through and crimp using a cold chisel. Something like this might have popped off and the cable can now just pull out from the backplate on one side.
  10. Just did a very quick search, loads of hits, this one most recent and looks to answer your questions. https://www.rhocar.org/index.php?/forums/topic/39046-cooling-system-diagram
  11. Yes that certificate is the SVA approval, same as for mine in January 2000. The SVA included an emission test, Limits were %CO by vol 3.5 and HC ppm 1200. The engine is/was as per the Sierra donor, twin choke downdraft carb (Weber DFTH 30/34) and no catalist. The actual tested values were 0.34 and 745 respectively, well within the limits. I have had several MOTs since, some have re-measured the emissions against these limits and earlier ones just didn't test, I don't know how they managed to do that and I didn't ask.
  12. The letters LP on the engine serial number indicates that the block was manufactured August 1990. The link below, is to an online copy some of the Haynes Manual, some chapters are missing. The Chapter on the Pinto (SOHC) engines is present, it does cover a lot of engine rebuild and specifications of parts etc however it's not a detailed workshop manual. It is more like a guide in places. https://www.leschroniquesdegoliath.com/wp-content/uploads/2018/01/Ford-Sierra-Service-And-Repair-Manual-GB.pdf
  13. I have attempted to make sense of the IVA Manual sections 20 - 30. There is nothing about any lamps having to be mounted vertically. The requirement for all the lamps is specified by the "angle of visibility", both horizontal and vertical. Also the lamps cannot be tilted so far that less than 50% of their apparent surface is visible from anywhere in the required angle of visibility. I guess to be absolutely certain a lamp is acceptably mounted one would need some trignometry and a measuring stick vertically at a known distance from the lamp. Mark the horizontal height of the lamp on the stick and the distance above that gives the correct angle. Plonk the stick vertically on the floor at this distance and look towards the lamp from just behind the stick. More than 50% of the apparent surface of the illuminated lamp then must be visible at least from the bottom mark all the way to the top mark. Oh yes, you must then move this stick around in an arc to check that it satisfies the vertical visiblity at all points of the horizontal requirement. This is easy because you can fix the bottom mark on the stick to the bottom of the lamp and just move the stick around keeping the string taught. Sounds complicated ... but a low tech measurement. Oh yes, there is all the other stuff about height of lamps and distance from the sides of the body ... thats easy. The only place I had trouble with the old SVA was the front indicators, on the EXMO the build instructions were to place them on the suspension outrigger below but closer together than the headlights. This position failed the horizontal visibility check, as the nose cone obscured the full extent of the angle (45 dgrees I think). Anyway I was surprised as to how far out of the nose cone sides I had to mount them on stalks. Iv'e seen cars since that must fail this test, my guess is that it was changed as soon as SVA/IVA was passed.
  14. I will also be needing to replace the shock absorbers on an EXMO at some time in the future, they are okay at the moment. The last postings regarding this, I believe, were in the thread https://www.rhocar.org/index.php?/forums/topic/27038-exmo-suspension/page/4/. Might help.
  15. This is an old chestnut. I have picked up lots of scraps of info from this and other forums over the years. In my amalgamated text file I have the following line. 'I' OR 'L' stamped next to number 4 spark plug hole= a leaded head most likely to be 1979 - 1982 in age. Now you are wondering about the age of your engine. Find the engine number stamped on the offside, near the front, should also match the V5 document. It should start with two capital letters. Then look at the attached screen grab from Burton Power to find the month and year of manufacture. For example my engine number has FR (June 1985) .... notice another FR in Oct 1966 .. cant be for a Pinto though. Oh! yes, also this assumes that the cylinder head and block are the original pairing.
